Cooler Master MM730 Review: Bigger Footprint, Still the Lightweight

The last Cooler Master mouse we got to look at was the MM711 and it’s an interesting take on how light a mouse can be: super lightweight with a design so bizarre that it was the talk of the town. I liked it but I wished it had some features that suited my taste. The folks heard that and surprised us with a mouse and lighter than the MM710/11. Dive into this Cooler Master MM730 review to see if you should get it.

Cooler Master MM730 Review

Look and Feel

The Cooler Master MM730 comes in two colorways: a completely black finish which looks basic if you ask me, and then there’s the white with grey accent which is what we have here and happens to be our favorite choice of color.

If you think the Cooler Master MM711 is as light as it can get, well, the Cooler Master MM730 is on a whole another level of lightness weighing in at 48g (vs. 53g MM711) and seeing that they have done the entire lightweight construction without adding any holes like the MM711 makes someone who has Trypophobia (fear of holes, don’t google.) – makes it more appealing for users seeking for mouse of that kind of weight.

As much as I enjoyed using the Cooler Master MM710/711, there were some things I would change for good, and boy does this Cooler Master MM730 answers all my prayers. For starters, if you are one of those users who prefer a mouse that’s bigger and has a nice hold in your hands, the MM730 does it right with a body that’s ergonomically comfortable and brings back good memories that I had with my ROG Gladius.

Unfortunately, the body of the mouse is extremely specific to right-handed users. So, users that need a left-handed mouse or an ambidextrous mouse – this MM730 is not for you. Otherwise, the Cooler Master MM730 feels nice, glides right on the table with its PTFE feet – not something you see in a lot of mice as it’s meant for enthusiasts who need that swift wrist action.

Now yes, there’s a chance that the mouse can fly off your hands (true story, been there done that.). So, they have included some grip stickers for you to hold the mouse nice and tight.

Specification

Specification-wise, the Cooler Master MM730 has the right kind of numbers that would get a gamers head turning.

• LK Optical Mouse Switch (Red) for the buttons
• Optical Encoder Scroll Wheel
• Pixart Optical Sensor for tracking
• Up to 16000 dpi, 1200 dpi in default mode.

Customizability

As I mentioned earlier, one customizable aspect of this mouse is the grip stickers that helps you have a better grip of this mouse in your hand which is a neat touch. Otherwise, you have plethora of controls which you can adjust and the granularity in MasterPlus+ app is good enough for you to play with. You can adjust the DPI profiles, Polling rate, RGB controls, setup macros and update the firmware.

1/5

Now say if the mouse switch wears off, it does look like it’s easy to replace BUT remember that the polycarbonate build of this mouse is fine, in a sense that if you try to pry it out with force or even with your nails, the plastic shell will have dents. So, be incredibly careful.

Experience

After using it for more than 2 months, we have a lot of things to say about the Cooler Master MM730. Coming from mice that have better ergonomic and jumping over to the MM730 was good as the form factor is something I genuinely appreciate. The 49g weight on the other hand, takes a lot of time to get used to, especially if you are coming from heavier mouse such as the MX Master 3 or Gladius from ROG.

Once you do get used to it, it’s a breeze to use as you barely feel like you must make an effort to move the mouse around; be it in games or just normal use case scenarios. One thing I do wish it did better is the Ultraweave cable which it comes attached to, permanently. Having a hot swappable cable would be nice, especially if you bring the mouse around to your neighborhood café, and you don’t want the super long cord to get in the way. Unfortunately, it’s something you will have to deal with unless you are keen on getting your hands on the Wireless version which does come with a removable USB-C cable.

Another thing to take note is that, if you are the kind of person who grips the mouse with your palm or do that “claw” grip – it works alright. But it’s not the most comfortable mouse to use if your grip type is fingertip and for that you’d need a shorter base mouse like the CM MM711 as it’s smaller both in height and length.

The extra buttons on the sides for your thumb is sensitive and say if you don’t want it to do anything, you can always turn it off in the MasterPlus+ application. Now, the scroll wheel is different from our traditional mechanical ones. The MM730 uses an optical scroll wheel which uses light to detect if the wheel is moving.

Now, good news is that it works but there is a design flaw where the rubber sleeve on top of the scroll wheel which tends to make the “scroll wheel” not move or slide off. This is pretty concerning because it can make the whole experience worse. So, we spoke to Cooler Master, and they have fixed it, so now the retail version no longer has that issue – which you do not have to worry about.

Personally, I use higher DPI mouse for things like editing which gives me that exact granularity when I try to do some Magic Wand crop on Photoshop – while you might wonder why higher DPI, mice like this has a better lower DPI range which gives you more control and that’s great to have.

As for gaming, I used the MM730 to play games like Division 2, Back 4 Blood and GTFO and it’s in these kinds of games where the higher DPI excels in giving the exact almost instant response you need. You can toggle the DPI profile depending on your situation but for some odd reason, Cooler Master moved the DPI button to the bottom of the mouse – another thing I don’t fancy.

This feels like nitpicking but the Cooler Master MM730 uses an LK Optical Switch for the buttons instead of the Pixart switches which we saw with the MM711. We have used both Pixart and Omron in the past and it’s safe to say that these two brands hold the fort for being amazing switches through and through.

While the LK Optical switch doesn’t instill the kind of confidence but knowing CM claims that it lasts for up to 70 million clicks and in the two months we have used, we have not noticed a case of anomaly which is good and hopefully it stays that way.

RGB-wise, it’s all right and it isn’t going to blow anyone’s mind of but if you are someone who don’t like a strong RGB, then you will love it as the only spots you will see the colorful lights glowing are through the scroll wheel and the CM logo on the body.

Conclusion

For those who are seeking that lightweight and classic ergonomic body of a mouse with some performance that’s going to give them the best kind of wrist action in games, the Cooler Master MM730 is the right kind of mouse. Given that it answers all my wishes that I had with the Cooler Master MM711 like bringing back the classic build and better ergonomic, which was my main concern.

There is room for improvement and the next thing I do want to see is: detachable cables for different occasions and we have a winner in my books. We are giving away one very soon, so make sure to hit the like and follow on our socials to stand a chance to walk away with this Cooler Master MM730.

Special thanks to Cooler Master for providing the MM730 for making this content happen.
